Re: Lance's 50khz playroutine

Hi there!

@Paulo, I just read your work on reverse engineering my old replay routine and I am extremely impressed. The routine itself was the pinnacle of what I did on the STE and was the result of intense competition with New Core (those guys were very smart) over 3 years. In other words; coming up with it was damn hard but I suspect reverse engineering it, improving it and understanding it must have been 10x harder.

I can talk for hours about the evolution of the code but I won't bore you.

Hats off to you Paulo,

Lance

PS. I still remember when I realized that move.b d0, (sp)+ worked on odd addresses as well as even addresses and I think this is the finest trick I did come up with (not saying that I was first because I honestly don't know). This was also the reason the routine switches to user mode, in order to allow interrupts during resampling but I guess you already figured that out.
